GENERAL INFORMATION
1-1, INTRODUCTION
1-2. This manual provides information pertaining to the installation, operation, testing, adjust¬
ment, and maintenance of the HP Model 5355A Automatic Frequency Converter and accessories.
1-3. Figure 1-1 shows the HP 5355A and accessories. The5355A isa piug-in unit for the HP5345A
Electronic Counter. The 5356A, 5356B, or 5356C Frequency Converter Head extends the
frequency range of the 5355A.
1-4. SPECIFICATIONS
1-5. Instrument specifications are listed in Table 1-1. These specifications are the performance
standards or limits against which the instrument may be tested. Specifications are based on
operation with the HP 5345A Electronic Counter.
1-6, INSTRUMENTS COVERED BY MANUAL
1-7. This instrument has a two-part serial number. The first four digits and the letter comprise
the serial number prefix. The last five digits form the sequential suffix that is unique to each
instrument. The contents of this manual apply directly to instruments having the same serial
number prefixfes) as listed under SERIAL PREFIX on the title page.
1-8. An instrument manufactured after the printing of this manual may have a serial prefix that is
not listed on the title page. This unlisted serial prefix indicates that the instrument is different
from those documented in this manual. The manual for this instrument is supplied with a yellow
Manual Changes supplement that contains change information that documents the differences.
1-9. OPERATING MANUAL
1-10. Packaged with this manual is an Operating Information Supplement. This is simply a copy
of the first three sections of this manual. This supplement should be kept with the instrument for
use by the operator. Additional copies of the Operating Information Supplement or the
Operating and Service Manual can be ordered through your nearest Hewlett-Packard Sales and
Service Office (a list of these offices is provided at the end of this manual). The part numbers are
listed on the title page of this manual.
1-11. MICROFICHE
1-12. Also listed on the title page of this manual following the Operating and Service Manual
and Operating Information Supplement part numbers are Microfiche part numbers for these
publications. These numbers can be used to order 4- X 6-inch microfilm transparencies of these
publications. The Microfiche package Includes the latest Manual Changes supplement and all
pertinent Service Notes.

1-20. The 5355A plug-in unit, when used with a 5345A Electronic Counter provides measure¬
ments of CW or burst frequencies from 400 MHz to 1.6 GHz. Since the 5345A has a range of Oto
500 MHz, the 5345A/5355A combination offers frequency measurement capability from 0—1.6
GHz. Frequencies up to 40 GHz may be measured by use of the accessories described in the
following paragraph.
1-21. For higher frequency measurements, the 5356A, 5356B, or 5356C Frequency Converter
Head is used. The heads use the single sampler, harmonic heterodyne technique to downconvert
the Input signal frequency. The 5356A allows measurements from 1.5 to 18 GHz,the5356B allows
measurements from 1.5 to 26.5 GHz, and the 5356C allows measurements from 1.5 to40 GHz. The
head connects to the signal source and the attached 5V2 foot cable connects to the multipin
connector on the front panel of the 5355A.
1-22. Signals in the 0.4 to 1.6 GHz range are sent through a prescaier (divider) in the5355A to the
IF circuits. Signals in the 1.5 to 40 GHz range are sent through the down-converter head to the IF
circuits. The 5355A automatically acquires the input CW or pulsed rf signal and under control of
its microprocessors algorithm, routes the down-converted signal to the 5345A mainframe to be
counted and displayed.
1-23. SERVICE EQUIPMENT AVAILABLE
1-24. A kit of extender boards is available to allow servicing printed circuit assemblies while
extended from the instrument. The extender boards allow the assemblies to be extended from
their pi ug-in connectors for monitoring with appropriate test equipment. The HP part number of
the kit is 05355-60100. Refer to paragraph 8-183 for detailed information.
1-25. RECOMMENDED TEST EQUIPMENT
1-26. The test equipment listed in Table 1-3 is recommended for use during performance tests,
adjustments, and troubleshooting. Substitute test equipment may be used if it meets the required
) characteristics listed In the table.

2-6. Power Requirements
2-7. The 5355A does not require external ac power. Ail necessary power is supplied by the5345A
when the 5355A Is plugged in.
2-8. Operating Environment
2-9. The operating temperature range is 0°C to 55°C. If these limits are exceeded at the
installation site, auxiliary cooling or heating should be used to keep environment within limits.
2-10, Installation
2-11. To install the 5355A, proceed as follows:
a. On the 5345A, set POWER switch to STANDBY.
b. Pull the locking handle on the left side of the 5355A up to the horizontal position.
c. Slide the 5355A into the 5345A. Use caution to prevent damage to interface con¬
nectors at rear of unit.
d. Push locking handle down and toward the Instrument until it is parallel with the front
panel.
e. For operating Information, address switch settings, and connections to rear panel BNC
connectors, refer to Section 111.
2-12, Compatibility with 5345A
2-13. The 5345A must be in EXT GATE mode when the 5355A is in PULSE mode and must be in
INT GATE mode when the 5355A is in CW mode. If the GATE CONTROL switch on the rear panel
of the 5345A is left in INT position, then the proper gating mode is selected automatically in
5345A's that have Serial Prefix 1808A or higher. Older 5345A's with serial prefix 1744A and below
require manual selection of EXT GATE mode (for PULSE) and INT GATE mode (for CWl. However,
a minor modification can be added (see paragraph 8-13) which updates these units.
